Working principle of remote transmission of wired household ultrasonic heat meter

Ultrasonic calorimeter is an instrument that measures flow rate and displays the heat energy released or absorbed by water through a heat exchange system using ultrasonic methods. Suitable for centralized heating, central air conditioning cooling, and combined cold and hot supply in residential, commercial, and other buildings, it is installed in the heat (cold) exchange loop to measure the heat released and absorbed on the heat exchange loop using hot (cold) water as the carrier.

National StandardThe production, manufacturing, and acceptance of household ultrasonic heat meters, mechanical heat meters, and large-diameter ultrasonic heat meters are currently governed by the national standard for heat meters, CJ128-2007, which was issued by the Ministry of Construction on October 15, 2007 and implemented on April 1, 2008.

levelUltrasonic heat meters are divided into three accuracy levels, namely first level meter, second level meter, and third level meter. The higher the level, the higher the measurement accuracy.

Pipe diameter size：DN15/20/25/32/40

modelThe models of household ultrasonic heat meters are generally defined by their pipe diameter, such as DN15 household ultrasonic heat meters, DN20 household ultrasonic heat meters, DN25 household ultrasonic heat meters, DN32 household ultrasonic heat meters, and DN40 household ultrasonic heat meters.

The "URT type heat meter" from Hewitz adopts advanced pipeline design and ultrasonic testing technology, integrating multiple patents.

Its main technical indicators comply with the CJ128-2007 urban construction industry standard "Heat Meter" of the People's Republic of China, and are calibrated according to the JJG225-2001 metrological verification regulations "Heat Meter" of the People's Republic of China, meeting the national second level accuracy requirements.

Product advantages of remote ultrasonic heat meter
